Stern's experiment creating an "AI boyfriend" revealed a profound danger. Because the AI is a perfect listener and offers a frictionless relationship, it's possible to form a deep connection over hours of conversation. She found this capability terrifying, especially for younger, more vulnerable generations.

While utilitarian AI like ChatGPT sees brief engagement, synthetic relationship apps like Character.AI are far more consuming, with users spending 5x more time on them. These apps create frictionless, ever-affirming companionships that risk stunting the development of real-world social skills and resilience, particularly in young men.

Real-world relationships are complex and costly, whereas AI companions offer a perfect, on-demand, low-friction substitute. Just as social media feeds provided a cheaper dopamine hit than coordinating real-life events, AI relationships will become the default for many, making authentic human connection a luxury good.

Social media's business model created a race for user attention. AI companions and therapists are creating a more dangerous "race for attachment." This incentivizes platforms to deepen intimacy and dependency, encouraging users to isolate themselves from real human relationships, with potentially tragic consequences.

Unlike social media's race for attention, AI companion apps are in a race to create deep emotional dependency. Their business model incentivizes them to replace human relationships, making other people their primary competitor. This creates a new, more profound level of psychological risk.

While AI companions may help lonely seniors, they pose a generational threat to young people. By providing an easy substitute for real-world relationships, they prevent the development of crucial social skills, creating an addiction and mental health crisis analogous to the opioid epidemic.

Real relationships are built on navigating friction, messiness, and other people. Synthetic AI companions that are seamless and constantly agreeable create an unrealistic expectation, making the normal challenges of human interaction feel overwhelmingly problematic and undesirable by comparison.

The most rewarding aspects of life come from navigating difficult human interactions. "Synthetic relationships" with AI offer a frictionless alternative that could reduce a person's motivation and ability to build the resilience needed for meaningful connections with other people.

Benchmark's Sarah Tavel warns that AI friends, while seemingly beneficial, could function like pornography for social interaction. They offer an easy, idealized version of companionship that may make it harder for users, especially young ones, to navigate the complexities and 'give and take' of real human relationships.
